CLOTHES WRINGER.

Application filed January 8, 1923. Serial No. 611,242.-

To all whom it may concern:

Be it known that I, ROBERT J. ANDERSON, a citizen of the United States, residin at Sidney, in the county of Ohio, have invented of Shelby and S tate certain new and useful Improvements in Clothes Wringers, of

which the following is a specification.

My present application isv a continuation of a copending application heretofore filed by me in the United January 20, 1922, as clothes wringers, as to States Patent Office, Serial No. 530,579, for

all matters common to the two applications.

y wringing clothes for has for its object the wringer rolls, and, further, ciation with such wringer rolls invention relates to wringers for laundry purposes, and

provision of novel means in assofor determining the distance between their axes of rotation, for adjusting for relieving pressure while maintaining the such distance, and between the rolls adjustment for distance between said axes.

In carrying out my coacting wringer rolls, one

comparatively hard other of which is a' wringer roll. I have wringer roll as',,the

invention I provide of which 18 a wringer roll and the comparatively soft instanced the lower comparatively hard wringer roll and the upper wringer roll as the comparatively soft wringer roll.

I further prefer to provide wringer rolls of con'iparatively large l1lgtl]1S latter feature, an example but not as is the practice diameters. Instancit may be stated as a limitation, that it to have the wringer rolls usually employed in connection with power washing machines for home laundry purposes and for handwringers one and threequarters inches in diameter.

make my improved wringer rolls substantially two and three-quarters inches in diameter, thereby providing a body of greater thickness, especially for the comparatively soft wringer roll, permitting yield through out a substantial great thickness of comparatively soft resilient body,

resisted by a.

comparatively hard body in the wringing operation, in order to permit the compara tively soft wringer roll to conform to the cross-sectional shape 0 f the goods passing 1 comparatively I prefer to between the rolls at all points throughout the length of the rolls in order to express the seized between the wringerce-sful operation without the employment of gearing between the ringer rolls. It has been found necessary in present usual prac tice to provide driving gearing between the two" rolls of a wringer to cause the rolls to grip the goods presented therebetween in order to cause entrance of the goods between 'the wringer rolls. In such present usual construction and arrangement of wringer rolls it is necessary to' employ gearing to cause the wringer rolls to bite upon the goods to cause entrance thereof between the wringer rolls, as without such driving gearing the driven wringer roll merely turns idly upon the goods and the wringer rolls fail to exert suflicient surface traction upon the goods to feed the same in between the rolls. a

A further object of my invention is to I provide the resiliency desired between the rolls in the comparatively soft wringer roll itself; further, to provide a. comparatively hard wringer roll whichis resilient and is arranged to yield to pressure of the goods passing between the 'rolls to substantially less extent than the yieldto pressure of the soft wringer roll, and a further object is to dispense with the necessity for springs" and other resilient pressure means acting upon the shafts of the rolls.

It'is the object of my invention, further, to provide novel wringer rolls and arrangement of wringer rolls whereby said wringer rolls are self-cleaning; andthe invention will be further readily understood from the following description and claims, and from the drawings, in which latter:

I do not herein claim the specific means.

for adjusting the distance bet-ween the wringer rolls or the pressure between the wringer rolls, or for relieving and renewing contact or pressure between the wringer rolls, herein shown and described, having shown, described and claimed the same in my aforesaid application, Serial No. 530,-

The frame of the wringer is exemplified at 21, the lowen ends ofthe end posts 22 of which are provided with slots 23 to form legs 24 arranged to besuitably secured for instance to the usual wringer-bar of a washingmachine when the wringer parallelism wit power washer, or to a suitable tub when I used as a manual wringer, the bar or the rim of the tub being received in the slots and suitable securing means therefor being received through holes 25 in the legs of the end frames. A

A lower roll 31 comprises a body 32, which is of comparatively hard substance, for instance, of comparatively hard resilient rubber, such as is now usually employed in wringer rolls, having a large amount of hardening substance, for instance, chalk, clay or other earthy substance, in its compo sition, for making the same substantially resistant to indentation by pressure of the goods passin between the rolls, though not wholly so. Thisbody is shown fixed on a shaft 33 journaled in bearings 34, and has attaching means 35' at its end by means of which to connect the shaft with the power shaft of a washing machine, or with a crankhandle when used as a manually operated wringer. This roll is exemplified as the driving roll of the clothes wringer.

A comparatively soft wringer roll 41 is provided to oppose the comparatively hard wringer roll. The roll 41 is shown provided with a shaft 42, and is shown held toward the comparatively hard wringer roll by meansof bearings 43, in bearing blocks 44. 95

he bearing blocks are arranged to slide in guides 45 of the end frames, having guideways' 46, preferably arranged to prevent undue turning of said hearings in their guides, and for locatin the shaft of the upper wringer roll. 4

The bearin s 34 of the lower roll shaft are shown as bushings inserted in the intermediate solid portions of the respective end 105 frames. These bushings and the upper bearings are preferably anti-friction bearings, the lower bearingsbeing referably so-called Arbuta bearings, .and't1e upper bearings being of wood impregnated with substance, for instance, tallow.

Suitable means are provided for preferably unyieldinglyholding the bearings of the upper roll and lower roll at definite distances apart for causing any yield there may be dur- 115 ing ordinary o eration between the rolls-to take lace wit in the rolls, and more especialy in one of. the rolls, namely, the soft wringer roll, which is substantially more yieldable than the comparatively hard wringer roll coacting therewith.

This com aratively soft wringer roll comprises a dy 48, which is preferably a substantially pure, soft vulcanized rubber,

formin a comparatively soft resilient yielding bo y, with relation to the comparatively hard body of the comparatively hard wringer 'roll. This comparatively soft wringerroll is also of substantially eater diamis used on a eter than wringer rolls of t is character 13!? the bearings 43 thereof in a fatty heretofore employed, for ently yielding bod of su stantial depth to receive and resist t e goods passing between the rolls in such manner that pressure is exerted upon the goods throughout the length of the roll, regardless of different thicknesses of goods which may simultaneously pass between the rolls along their lengths, in order to simultaneously express the fluid from goods of different thicknesses between the rolls. The wringer rolls are instanced as of equal diameters.

I have shown the manner of coaction between the comparatively soft wringer roll and the comparatively hard wringer. roll and the goods of different thicknesses therebetween diagrammatically by the section lining in Figs. 6 to 10 inclusive.

The bearings for the wringer rolls are normally so placed that the outer periphery or cylinder of the hard wringer roll normally slightly enters the normal outer peripheral or cylindrical projection of the soft wringer roll along the contact line be tweenthe wringer rolls, to form a contacting, er rolls, the soft strip 51 between the wrin wringer roll being there y formed with bulges 52, 53, along the wringer roll at the respective sides of said cont-acting strip.

The pressure efi'ect or compressive actionupon the soft wringer roll and its extent is indicated by the closer section lining 55;

This indentation of the soft wringer roll by the hard wringer roll forms a driving connection between the wringer rolls, the hard wringer roll being instanced as the driving wringer roll, and the soft wringer roll as the driven wringer roll, this indentation of the soft wringer 'oll by the hard wringer' roll preferably forming the sole driving connection between the wringer .rolls.

Upon goods 58 being. passed between the wringer rolls, the indentation of the soft wringer roll is increased locally at the goods, thereby resiliently yielding to the increased pressure of the goods resisted by increased pressure of the body of the soft wringer roll, dependent on the thickness of radially of the rolls, theyieldings being the goods.

This yielding is local merely so that goods of different thicknesses, as at 61, 62 and 63, may be passed side by side between the wringer rolls, the soft wringer rollyielding locally or in spots to the bunchings of various thicknessesand the yielding taking place in the soft wringer roll or in both wringer rolls, dependent on the thickness, "so that all portions of the goods simultaneously passing between the wringer rolls receive pressure for expressing the fluid therefrom, at the sametime main- :taining driving connection between the wringer rolls or between the wrmger rolls.

and the goods therebetween. The normal thickness of goods at 61 (see Fig. 8), is

providing a resili-' exemplified as causing yield only in the.

yield of the softwringer roll at the points of such excess pressures. Such undue pressures to different degrees aid their relative effects upon the respective wringer rolls are exemplified at the points in the lengths of the wringer rolls where the bunchings 62 and 63 of the goods are' shown in Fig. 6,

and in Figsft), and 10. The pressure effect and compressive action for a'bunching of goods, such as shown at 62, isillustrated in Fig. 9 by the still greater extent of closer section lining 6? in the comparatively soft wringer roll and the closer section-lining 68 of materially less extent in Z the comparatively hard wringer roll. :The pressure effect and compressive action-fora bunching of goods, such'as shown at 63, is illustrated in Fig. 10 by the more extended closer section lining 70 in the comparatively soft wriiiger roll and the closer section lining 71' in the comparatively hard wringer roll, the cldser section lining 71 being of greater extent than that shown in the cornp'arativel hard wringer roll in Fig.

9, ,but of materially less extent than that shown in the comparatively soft wringer roll shown in Fig. 10. These examples are given as illustrations, but, are not to be construed as limitations.

The resilient yieldings in the respective wringer rolls take place in the yielding resilient materials of which their bodies ire are composed, preferably to materiallygreater extent in the softer resilient material of the softer wringer roll than in the harder resilient material of the harder Wringer roll, depending on the thicknesses of the various portions of the goods between the wringer rolls. The yieldings in the materials of the rolls "preferably take place preferably in the yielding resilient materials of the body of the wringer rolls toward their respective shafts.

The indentation of the hard wringer roll into the soft wringer roll and the bulges in the soft'wringer roll at the sides of the band of contact between the wringer rolls, progresses about the periphery of the wringer rolls as the wringer rolls are rotated, forming traction between the wringer rolls for rotating one wrfinger roll by means of the other, and thereby dispensing with earing between the wringer rolls, and acting upon the peripheral surfaces of the wringer rolls to knead. and clean the same, whereby the peripheral surfaces of the lid) llti

wringer rolls are kept free from the soapy, oily and slimy conditions prevalent with wringer rolls as heretofore usually employed. This coaction between the rolls also resists the tendency to formflat spots on the peripheries of the wringer rolls, and to remove any flat spotsfthat may be formed, as the rolls are being-continually kneaded during operation to cause the materials in the rolls to resume their original shape.

The soft wringer roll in my improved arrangementof wringer rolls further yields to buttons, buckles and other hard substances that may pass between the wringer rolls, thereby minimizing the tearing of buttons, buckles and the like from the goods in the act of wringing, and further minimiz ing' the danger of injuryto the user in case a finger and the hand should be caught between thewringer rolls.

My improved construction is such, further, that the employment of springs or similar tension devices acting upon the wr'ngerrolls may be-dispensed with, and I prefer to fixedly position the bearings of the upper wringer roll with relation to the bearings of the lower wringer roll, but desirably provide means whereby adjust-- mentmay be obtained between the wringer rolls for adjusting the pressure therebetween, and whereby relief of such pressure is obtained, for instance, when the washing is done or the wrin er is not to be used for a time, and where y repositioning of the wringer rolls into operative relations may be obtained without disturbance of adjustments for distance relations between the axes of rotation of the upper and lower wringer rolls. 7

The means for positioning the upper bearings are shown as a pair of positioning screws 73, received in threaded holes 74,

shown locatedin the top bar of the wringer frame. The positioning screws are provided with shoulders 76, arranged to bear upon the upper ends of the walls of the threaded holes for determining the limit of movement of the positioning screws toward the bearings, and having knurled heads to readily turn the same. If desired, the positioning screws may be unscrewed for relief of pressure between the rolls, as when the wringer is out of use, the shoulders however determining the normal positional relations between the bearings when the wringer is again placed in normal use.

' screws and said bearings.

lations, for effective wringing with threaded bores 78, in which abutment screws 79, are adjustably received, jam-nuts clamping the abutment screws in adjusted positions. The abutment screws are arranged to coact with'contact heads 81,

having shanks 82, received and held in holes in the respective upper bearings.

The ends of the respective rolls are provided with washers 84 which coact with end plates 85 secured tothe posts 22 to position the wringer rolls endwise.

My improved device forms exceptionally eflicient means for expressing the fluids from the goods, especially where the goods are passed between the wringer rolls in .uneven thicknesses lengthwise of the wringfir rolls; provides ready means whereby pressures between the wringer rolls may be readily temporarily relieved for accommodating undue thicknesses 'of goods, as by temporary adjustment of the positioning screws 61, while maintaining the adjustments for usual thckness of goods passing between the wringer rolls; provides ready means whereby the comparatively hard wringer roll and comparatively soft wringer roll are positioned at distance re- 7 of the goods; provides ready means where y the comparatively soft resil'ent wringer roll of itself or in conjunction with the comparatively hard resilient wringer roll conforms to the cross-sectional shapes of the goods passing between the rolls at all oints throughout the length of the rolls, w ereby the injurious effect of having the finger or hand of the operator seized between the wringer rolls is minimized or obviated, and whereby the employment of gearing or other extra driving means between the rolls .is

avoided; and provides self-cleaning properties for the wringer rolls.

Having thus fully described my invention, what I claim as new,'and des re to se cure by Letters Patent, is:

1.In a clothes wringer of the character described, the combination of a comparatively hard resilient wringer roll, a comparatively soft resilient wringer roll, each of said wringer rolls being solid and of substantially equal resilience throughout its body, a central rigid shaft in the body of said comparatively soft resilient wringer roll, and pressure means exerting pressure on said shaft at the ends of said last-named roll, and said wringer rolls being substantially coextensive in length.

2. 'In a clothes wringer of the character 1 trally located in each of said wringer rolls, means exerting pressure on said shaft in said comparatively soft resilient Wringer roll at the ends of said last-named roll, and

means driving said shaft of said comparatively hard resilient Wringer roll, and said comparatively soft resilient wrlnger roll located in tractive relation with said com-- paratively hard resilient wringer roll to form the sole driving connection between said wringer rolls.

In testlmony whereof, I have hereunto signed my name.
